Category	Niagen Plus	ReadyRx
Longevity & Peptides	$149 Niagen At-Home Injection Kit (NR chloride 500 mg, ~28 days)	$80–$130 MIC+B12

Niagen Plus

+Backed by a public company with 25+ years of NAD+-precursor research; it holds the patent on the active ingredient (Niagen NRCl)

+Compounded by a 503B outsourcing facility (FDA-registered, cGMP) rather than a patient-specific 503A lab alone

+Flat, published $149 kit price includes the provider consult, a ~28-day supply, supplies and free Next Day Air shipping

−Only one product, and it is NR (an NAD+ precursor), not NAD+; the studies comparing it with NAD+ IV are small and company-sponsored

−The kit showed 'more stock coming soon' at the time of research, so availability is not reliable

−The site does not name the telehealth medical group or the dispensing 503A pharmacy
